Time-slot-based system and method of inter-vehicle communication
ActiveUS8520695B1Efficient communicationEfficient codingInstruments for road network navigationArrangements for variable traffic instructionsWireless transmissionCommunications system
Device, system and method, in a vehicle communication system, to transmit wirelessly a message comprising the position, heading and speed of a vehicle or other moving object, wherein the transmission is repeated at regular intervals in a temporarily fixed time slot within a predetermined basic time interval. In a key embodiment the message duration is equal to or less than a predetermined time slot duration. Embodiments use generally the same time slot in a contiguous sequence of basic time intervals. Algorithms are described to resolve wireless interference within a time slot. Embodiments divide the basic time interval in multiple durations, “class regions,” for different message classes. Embodiments use different wireless bandwidth allocation algorithms for the class regions.

System and method for coordinating bandwidth usage of a communication channel by wireless network nodes
ActiveUS7248570B2Optimizing bandwidth usageNetwork traffic/resource managementNetwork topologiesTransmission channelWireless network
A system and method is provided for coordinating wireless bandwidth usage of a common frequency band by wireless nodes in two disjoint networks, such as an infrastructure (“IS”) network and an ad hoc (“AH”) network. When AH nodes move into the transmission range of an access point of the IS network, they register with the access point and listen to the access point to tell them when they are allowed to transmit data over a given transmission channel. The access point coordinates the bandwidth usage by broadcasting ad hoc mode poll signals to indicate that the ad hoc nodes may transmit over the channel, and sending infrastructure mode poll signals to indicate that a wireless node in the IS network can transmit over the given channel. The access point makes a fraction of the bandwidth available for communications by the wireless AH nodes in its transmission range, while guaranteeing the rest of the bandwidth for wireless nodes in the IS network.

Wireless networks and devices are ubiquitous today. For service providers to offer customers QoS and Service Level Agreements (SLAs) means in part providing resilient connectivity of wireless devices with good signal strength, good Signal to Noise and Interference Ratio (SNIR), and adequate useable bandwidth. Doing so requires that devices transmitting and receiving packets use over-the-air bandwidth efficiently and manage over-the-air congestion. According to embodiments of the invention QoS measurements and controls are incorporated only in the network (i.e. APs or controllers) and therefore QoS and SLAs can be achieved with all deployed client stations versus standards based approaches that require additional capabilities in network nodes, client stations and in most cases modifications to the applications. SLAs can be provided exploiting embodiments of the invention for traffic prioritization, capacity improvements through load distribution, and adjacent channel interference mitigation discretely or in combination with standards based mechanisms.

Quality of service over paths having a wireless-link
InactiveUS7079508B2Increase access probabilityReduce probabilityError prevention/detection by using return channelNetwork traffic/resource managementQuality of serviceBandwidth management
The invention provides Quality of Service assurances in a manner expected in other media to communications over paths that include one or more wireless links. The invention combines a subnet bandwidth manager (“SBM”) at an access point (“AP”) to track allocations of wireless bandwidth. The invention further incorporates multiple priority levels for packet transmission in a two-prong stochastic scheme. The first prong reserves bandwidth at each of the intermediate nodes in a transmission path subject to a veto by any intermediate node. The second prong modulates the transmission probability of a packet based on the previous failed attempts at transmission and the priority level of the packet. The overall result of this hybrid scheme is to not shut out users with the lowest priority, e.g., “best effort” priority, while assuring adequate bandwidth to higher priority applications.

Wireless docking station
InactiveUS20050246470A1High bandwidthImprove reliabilityDigital data processing detailsDocking stationData rate
With the rapid innovation in wireless technology, greater bandwidth is now available. This invention proposes to use the much greater wireless bandwidth available with ultrawideband (UWB) technology, to replace the current expensive solution for laptop port replication using hardwired connections. First, a wireless interface between the laptop and the port replicator will no longer require the expensive, high-pincount docking station connector currently in use in today's products. This will increase reliability of the docking system, and decrease cost of the solution. Second, a wireless dock will allow the laptop user to more quickly associate their computer with the docking station and connected peripherals merely by placing the laptop in proximity with the dock. Third, the bandwidth of the UWB wireless connection can be superior to that of a USB solution, with data rates exceeding 1 Gbps. When these advantages are combined, the UWB-powered docking station will offer a significant alternative to the current approach for laptop docking while protecting the customer investment in peripherals.

The invention discloses a centrally controlled time division multiplexing wireless communication micro base station network. The conventional wireless technology can only provide a narrow-band service because of the limitation of bandwidth and quality. The wireless bandwidth can be promoted only by three methods, namely increasing a used frequency range, improving the frequency spectrum efficiency and increasing a frequency spectrum multiplexing rate. But both the two methods, namely increasing the used frequency range and improving the efficiency, have impassable theoretical boundary, and only the method for increasing the frequency spectrum multiplexing rate has potential of being partially increased by over ten thousand times. Therefore, the method for increasing the frequency spectrummultiplexing rate becomes an optimal way for meeting the future application of the wireless broadband. The centrally controlled time division multiplexing wireless communication micro base station network solves a series of problems caused by the high-density micro base station network architecture. The main properties of the centrally controlled time division multiplexing wireless communication micro base station network greatly surpass the conventional mobile communication technology and the quality and capacity of the wireless network are promoted to a level approximate to the wired network for the first time.
